CONDENSATE OIL-GAS MIXTURES PHASE BEHAVIOR STUDY WITH RICH GASEOUS CONDENSATE WATER
富含凝析水的凝析油气体系相态研究

The common oil-gas mixtures phase behavior study ignores the influence of formation water, which is classical but not considering the strong polar material. For the existing of polar material water, the condensate oil-gas mixtures phase behavior study with rich gaseous condensate water is different from the common phase behavior study. In the process of study with rich gaseous condensate writer, the oil and gas reservoir is under abnormally high temperature and pressure which could influence tire choice of expert mental facilities, the design of experimental process flow. And the traditional thermodynamics models should be adapted. With more and more natural gas exploited in deep reservoir,some special condensate gas reservoirs with rich gaseous condensate water in abnormally high temperature and pressure are emcrg ing continuously. When the formation under tire condition of high temperature, more and more bottom wa ter, edge water and aetive porous water will coexist with condensate gas in vapor. If we still use convcn tional behavior study ways in such special condensate gas reservoirs,it will result in many errors in produc ing methods,engineering design and performance analysis. This paper prescnted the methods and meaning of phase behavior study with rich gaseous condensate water,in the meantime ,presented a Calculation rood el of gas-liquid-liquid 3-phase equilibrium of condensate oil-gas mixtures with rich gaseous condensate wa ter.
